Foam and Lights

Five identical, roughly door sized boxes are filled with insulating spray foam. Protruding from each are five light fixtures, which are switched by the heat of the neighboring bulb. When the boxes are plugged in, one bulb on each is lit. The remaining lights turn progressively on and then off. The entire cycle takes about 25 minutes for each box, with one of the 25 bulbs switching audibly about every 30 seconds. This piece uses construction materials, usually invisible inside walls, to enhance the sense of interiority created by the wall coverage and the slow changes in light and heat.
